Description

【0001】
【発明の属する技術分野】
本発明はマイクロ波を受信し周波数変換し増幅し、出力するマイクロ波用コンバータに属する。特に1枚の基板上に電波の取入口と高周波回路及び電源回路等の高周波回路以外の回路とを設けたマイクロ波用コンバータに属する。
【0002】
【従来の技術】
従来、基板上に形成された電波の取入口に高周波回路をRF増幅部,フィルタ部,ミキサ部,局部発信部,IF増幅部などの順に順次直列に配置、接続されるとともにその隣接した位置に電源回路等の高周波回路以外の回路を配置した構造のものがあった。
【0003】
【発明が解決しようとする課題】
しかし、マイクロ波用コンバータの場合、取り扱う周波数が高い上に微弱な信号が伝送されるため、上述した回路配置とした場合、電波の取入口から離れるに従い、高周波回路のアースの電位に差を生じることにより高周波回路のアースが不安定になったり、高周波回路と直流回路やアース配線とが交差する場合が発生し、NFが悪化したり発振しやすくなる等、特性が劣化する原因となっていた。また、このような点を考慮したイアウトが考えられているが、アース等の配線の複雑さは解消されず、特性を改善し得るものではなかった。
特に、電波取入口はその位置やアースの配置,形状によって特性が大きく変化するもので、良好でしかも安定した特性を有するマイクロ波用コンバータを得ることは基板設計において常に難しいものであった。
この点に鑑み、本発明は回路の配置やアースの配置、形状等に苦心する事無く良好な特性を得ることができるマイクロ波用コンバータを提供するものである。
【0004】
【課題を解決するための手段】
上記課題を解決するために、本発明によるマイクロ波用コンバータは、ケース内に高周波回路と高周波回路以外の回路とを組付けた基板を導波管の電波導入方向に対して直交配置し、前記基板には電波の通路に電波取入口を形成し、一方の面をアース面、他方の面を回路形成面とし、電波取入口を基板中央又はその近辺に配置すると共に前記高周波回路を前記電波取入口を囲むように配設し、更にその各高周波回路に電源を供給する電源供給ラインを電波取入口を中心にして前記高周波回路の外側に配置して構成される。
【0005】
【発明の実施の形態】
本発明を具体化した一実施形態を図面に基づいて説明する。
図1は本発明のマイクロ波用コンバータの基板の正面説明図で、各回路ブロックの配置と電波取入口の配置を示している。この図に於て、4は電波取入口で基板中央に配置され、5,6は導波管内に導入された電波を取り入れるためのプローブであり、7aは導体棒7の挿通口である。この導体棒7は受信特性を良好にするために、導波管の短絡壁から突設され基板1の電波取入口4を貫通する長さを有し、そのため基板上の電波取入口4中央には、この導体棒7を挿通するための挿通口7aが設けられている。
【0006】
そして、高周波回路であるRF増幅部12,フィルタ部13,ミキサー部14,局部発振部15,IF増幅部16がその近接する周囲に配置され、それ以外の電源回路11と各回路への電源供給ライン11aがその外側に、高周波部を取り囲むように配置され、裏面は電波取入口4以外を銅箔で覆いアースとしてある。また、17は信号を送出するための信号送出部であり、19は電力分離フィルタ部である。
【0007】
図2は図1の基板1をケースに取り付け、導波管と基板の関係を示す略断面図である。この図において基板1は、導波管8を有する箱体2と導体棒7を有する蓋体3からなるケース内に導波管8に垂直になるよう取り付けられ、8aは蓋体側導波管、18は短絡壁であり、10はホーンである。
また、導波管8は円形導波管で、電波取入口4の外周は対応する導波管8と同径の円形形状であり、基板1取付により電波取入口4の外周は導波管8,8aと密着し、電気的に導通するようになっている。
尚、プローブ5,6は夫々水平偏波,垂直偏波に対応するよう配設されていが、電波取入口は電波導入位置の形状に合せ円形でなくともよく、受信するプローブは受信するマイクロ波に合せ1本であってもよい。
【0008】
図3は、図2の構成の詳細を示した分解斜視図である。図3に於て、基板1は中央位置に電波取入口4の外周部が銅箔アース部20aにより形成され、このアース部20aは後述する蓋体3′の導波管8aと密着するようになっている。また、導波管内に導入された電波を取り入れるためのプローブ5,6が銅箔パターンで形成されている。なお4aは電波取入口4を形成する銅箔を剥離した部分である。
基板1の裏面は電波の取入口4を除くほぼ全面に銅箔を設けアースとし、回路形成面のアース部とは適宜スルーホール等で連結されている。図4は基板1のアース面の斜視図であり、4bは電波取入口4の裏面で銅箔を剥離した部分である。また、20はアース部、21は取付ねじ挿通孔でもあるスルーホールであり、22はジャンパー線である。このジャンパー線22の反対面が信号送出部となっている。
【0009】
箱体2には、基板1の電波の取入口4と一致し、基板1と垂直に交差する導波管8が形成され、その先にホーン10を有している。また、側面にはコンバータにより変換された信号を同軸ケーブルに送出するためのコネクタ9が形成され、コネクタ9の中心導体の箱体2内側には基板1の接続部1aとの連結部を有し、基板1取付時に信号送出部17と接続される構成となっている。
【0010】
また、3′はシールド用蓋体であり、基板1上の高周波部をシールドするもので、ネジ等で基板高周波部を密閉し外部から電波が侵入、あるいは外に漏れないようにするためのものである。尚、使用する際に、ケースはさらに風雨から内部を保護するために合成樹脂等で成形されたキャップ(図示せず)を箱体2,蓋体3′を覆う形で箱体2の枠部全体にはめ込み密閉させて構成される。
【0011】
さらに、このシールド用蓋体3′は、図2において示しているように内側に円形導波管8の電波導入位置で基板1により分断された導波管8aと短絡壁18を有し、短絡壁18中央には導波管の軸線方向に伸びる導体棒7を形成してある。尚、基板1の材質は高周波特性の良いものであればよく、例えばフッソ樹脂製のものを用いればよい。また、箱体2とシールド用蓋体3′は導電性の良い金属製であり、例えばステンレス等の金属板をプレス成形したものであっても良いが、アルミのダイキャストであれば、導波管8,ホーン10等と一体成形することができ良い。
【0012】
このように、電波取入口4を中央に配置し、その近接するアースの電位が均一である周囲に高周波回路12〜16を配置し、更にその周囲に電源11を始めとするその他の回路というように配置することで、高周波特性を劣化させる事無く各回路を無理なく配線し接続することができる。例えば高周波回路12〜16と電源11の接続は、電源の供給ライン11aを基板周囲に張り巡らすことで、いずれの場所でも容易に接続することができる。
【0013】
従って、裏面のアース部20は、表面の回路配置が基板中央の電波取入口4を中心にその近接する周囲に高周波回路、更にその外周に電源回路等の高周波回路以外の回路を配置しているため、ほぼ全面を一様なアース面とするだけで中央付近のアースバランスが良好となり、微弱な信号を扱うため最もアースバランスを必要とする電波取入口4をこの位置に配置することで、アースの配置,形状に腐心する事無く、高周波回路は良好な特性を示し安定した動作をする。
【0014】
尚、この実施形態においては、導波管の電波導入方向に基板のアース面を向け、導波管の短絡面側を回路形成面としたが、裏返して電波導入方向が回路形成面であってもよい。また、シールド用蓋体3は箱体2全体を覆う形状とし、風雨から回路を保護する蓋体と兼用としても良い。
【0015】
【発明の効果】
以上述したように、本発明によれば基板のほぼ中央に電波取入口を配置しその周囲に高周波回路、更にその外側にその電源供給ラインを配置したので、回路の各ブロックの配置やアースの配置,形状に苦心することなく、損失が少なく良好な特性を有するという優れた効果を奏することができる。

[Problems to be solved by the invention]
However, in the case of the converter for microwaves, a high frequency is handled and a weak signal is transmitted. Therefore, in the case of the circuit arrangement described above, a difference occurs in the ground potential of the high-frequency circuit as the distance from the radio wave intake is increased. As a result, the grounding of the high-frequency circuit becomes unstable, or the high-frequency circuit and the DC circuit or the ground wiring may cross each other, resulting in deterioration of characteristics such as deterioration of NF or easy oscillation. . Further, although it is conceivable to consider such a point, the complexity of wiring such as grounding is not eliminated, and the characteristics cannot be improved.
In particular, the characteristics of the radio wave intake vary greatly depending on the position, the arrangement and shape of the ground, and it has always been difficult to obtain a microwave converter having good and stable characteristics.
In view of this point, the present invention provides a microwave converter capable of obtaining good characteristics without being troubled by circuit arrangement, earth arrangement, shape, and the like.
